KN-92 is primarily used in research settings to study cellular processes and signaling pathways. It is often employed as a tool to investigate the role of specific kinases in various biological functions, including cell proliferation, differentiation, and apoptosis. Researchers utilize KN-92 to understand the mechanisms underlying diseases such as cancer, inflammation, and neurodegenerative disorders. Additionally, it serves as a reference compound in experiments to validate the specificity and efficacy of other kinase inhibitors. Its application extends to drug discovery, where it helps in identifying potential therapeutic targets by modulating kinase activity in experimental models.
